|James Webb Space Telescope Mirrors readied for cyrogenic testing|
Three of the 18 James Webb Space Telescope mirror segments were mounted on a test stand July 30 at the X-ray & Cryogenic Facility at NASAs Marshall Space Flight Center in Huntsville, Ala. The mirror segments are being moved into the facilitys cryogenic vacuum chamber, which will chill them to minus 414 degrees Fahrenheit to ensure they can withstand the extreme temperatures of space. As this cooling takes place, engineers and technicians from NASA and Ball Aerospace & Technologies Corp...

|Successful Small-Scale Rocket Motor Test|
Engineers at NASA's Marshall Space Flight Center in Huntsville, Ala. successfully tested a sub-scale solid rocket motor on May 27. Testing a sub-scale version of a rocket motor is a cost-effective way to evaluate new materials, technologies or processes, and rapidly assess performance. Data from the 21-second test will be evaluated to better understand the performance of a new nozzle configuration, processes and materials.

|NASA Ares I Rocket - Yuma Drop Test|
Unfurling in majestic patriotic colors, a successful cluster test of the Ares I rocket's three, 1-ton main parachutes was conducted May 20 by NASA and industry engineers at the U.S. Army Yuma Proving Ground located near Yuma, Ariz. The main parachute is designed to slow the rapid descent of the spent first-stage motor and permit its recovery for use on future flights.

|'Focus on Marshall' in Utah for Historic Motor Test|
A legacy of smoke and fire is celebrated in the May episode of "Focus on Marshall." The "Focus on Marshall" team traveled to Promontory, Utah, for the final ground test of a space shuttle solid rocket motor in February. The test was conducted to ensure the safe fly-out of the remaining space shuttle missions. A total of 43 design objectives were measured through 258 instrument channels during the two-minute static firing...

|NASA's Robotic Lunar Lander Development Test Project|
During recent tests at NASA's Marshall Space Flight Center in Huntsville, Ala., the lander test article was suspended up 10.5 feet from the landing pad. After being released from its hoist, the lander simultaneously received a command to activate its onboard thrusters to carry it to a controlled landing using a preprogrammed descent profile. These tests demonstrate the test article's capability to perform autonomous descent, and soon will be used to checkout landing control algorithms for the ne...
